Serial m. 4510,G8019 My inventionrelates to working heads for windmills, pump jacks and the like; and theobject is to provide simple and economic construction of devices for.use as windmills,

and the like and to provide the construction and devices with automaticlubricating means. The advantage of the improved construction isthat-"it is simple and compact and easily installed'and easily operacenter lift of the load is obtainedr Other objects and advantages willbe fully explained in the following description and the invention willbe more particularly pointed out in the claims. 7 Reference is had tothe l accompanying drawings which form a part of this applica-r indicatethe same 1 V eral views.

Similar characters of reference are used-to parts throughout the sev-The'pump head is provided with a housing in two 'parts,the upper part 1cooperating with the lower part 2 which forms thelubricating reservoirand both parts inclosingthe operatingparts. The main driving shaft 3 isjournaled in bearings 4 and 5. The bearplace by the cap ,6 which isattached to the horizontal reservoir housing 7 by means of screw bolts8. The bearing 5 is held in place by the cap 9 which i's'attached to thehousing member 2, and by screw bolts 10.

A pinion 11 is rigid withshaft 3. and is driven by this shaft. Thepinion 11' drives the cog wheel 12 which isrigid with the crank shaft13, shown in'Fig. 4c. The crank shaft 3 '13 is journaled in bearings 14which are at- V tached to housing member 2. See Figs. 2 and 3. .Thebearings 14 are held'in place by'caps 15. The shaft 13 actuates thepiston rod 16.

- What I claim, is,

1. A working head for windmills, pump jacks, and the like, comprising ahousing in upper and lower'parts, a driving shaft and gearing. actuatedby said driving shaft for driving said crank shaft, said lower part oriaid housing serving as a lubricant reservoir,

a piston rod adapted to move vertically in said housing, aguide bearingforsaid piston rod, a driving head rigid with said piston rod andactuated by said crank,sh af;t,-alubricant distributer carried by saiddriving head for delivering lubricant to said guide bearing and totlieworking parts of saidjworking head, and means actuated by saiddi'stributer for delivering lubricant from said reservoir 10 saiddistributer.

2. A working. head for windmills, pump jacks and the like comprising ahousing in upper and lower parts, a guide bearing rigid with said upperpart and pro ecting-.within he housing, a protecting cap rigid with saidhousing for a-pisto'n rod, a piston rod movable vertically in saidhousingfand in said cap, meansfor operating said piston rod; adistributer rigid with said piston rod and wrovided with a cavity in itsupper face, said lower part of thehousing constituting an oil reservoir,a cylinderprojecting'down in said reservoir and made stationarytherewith, a

hollow plunger'rod carried by said distrib 'ter andprojecting-down insaid stationary cylinder and carrying a hollow, plunger, said cylinderhaving intake ports and. said rod forcing oil upwardly intofsaiddistributer 7 when said plunger is forced below said ports, M and meansfor preventing oil from following said pistonrod down into a well.

3. A working head for windmills, pump? jacks, and the like' comprising ahousing in upper and lower-parts, the latter forming an oilreservoir,*aguidebearing'rigid with said upper housing andconstitutingin part means forlubricating afpiston rod, a plston rodmoving vertically 1n said housmg; and

through said guide into said cap, means for rotuating said piston rod,adistributer rigid with said piston rod and prov ded with a Icavlty'inits upper face for supplying oil to '1 said guide, meansactuated by said distributer for supplying oilthereto, and means forpre-. enting 011 from' followingsald piston rod down into the wellconsisting ofan upstandmg tubular pipe rigid with 'said lower housingand proJecting above the oil in said resertent oil from entering saidupstanding pipe. In testimony whereof, I setmyhand, this 21st day ofMarch, 1930.
